To all whom it may concern:

Be it known that of the United States, residing-in thecity of Brooklyn, in Kings county and State of New 5 York, have invented thefollowing-described I Improvements in' Internal-Combustion Engines.

of: the valve ports and valves for lnternal combustion engines having rotary having labyrinth valves as hereinafter de-' scribed, the object being an eiiicient, compactand and particularly adapted for multi-cylinder' engines in which the cylinders are closeset inairow: 1

In the engine illustrated the cylinders 1, 2, 3 and 4, are cast in pairs, although they might be otherw1se,- and are mounted on a suitable base with which. they form a'crank case inclosure, as usual. The head-structure, in one or more parts, ders and provides within it an L-space 5, or lateral chamber extension, for each vcylinder, at or near the top hereof. These spaces. or lateral passages -5, extend in opposite direc tions above each successive cylinder in the row, so that on the first and third cylinders they are on the right-hand side and on the second and fourth cylinders they are on the left-hand side. Both-the intake and exhaust gases pass through these 7 passages,
